SERS Study of Methyl Orange on Metallic Silver Nanoparticles
JIA Ting-jian;School of Electrical and Electronic Engineering,Shangqiu Teachers College;
The Normal Raman spectrum(NRS) of methyl orange(MO) was observed in this paper and presents theoretical vibrational spectra calculated from a Gauss 98 software on the basis of B3 LYP with 6-31 basis set. The calculated results show very good agreement with the experimen-tally observed Raman frequencies. We also report the surface enhanced Raman spectrum(SERS) of MO adsorbed on silver nanoparticles surface. Finally, the possible adsorbed state of MO on the silver nanoparticles surface is discussed.
